'Coinhination Stop Mechanism for Organs;

and X do hereby declare the following to be full. clear, and exact description of the aine, reference being had to the accompanying drawings. forming a part of this specification and to the referencenumerals marked thereon.

The present invention relates to musical instruments and more particularly to or! gens or instruments constructed on the general scheme out an organ, and it has for an object to provide asimple andetiicient switch mechanism tl'irougjh the medium of which certain parts of the organ may be thrown into or out of operation.

it further object of the inVe-ntioi'i is to provide an electrical switch of this nature" for electin-pneumatically operated organs having on and oil positions, in one or both of which it is retained mechanically against movement to the other.

The improvements are further directed toward improving the stop mechanism of the organ by simplifying and making more convenient and certain in operation the switching devices whereby the different stoplieys of a manual are selected on the different combination keys orpist-ons, as they are called.

To these and other ends the invention consists in certain improvements and. combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the sg'ieeilication.

In the drawings: Figure I is a top plan view (it a switch mechanism constructed in accordance. with and illustrating one anbodiineiit (it my invention; Fig. 2 IS a ver- .L v L tical section therethi'ough taken substantially on the line 22 of Fig. 1 and showing in similar section the wind-supply-mecha- 111S111'f01 the motors; Fig. is a section taken substantially on the line 3-43 of 1 showing one of valve iiieinliei's for controlling the motors and its operating; means; Fig. l is a diagrammatic View showing that portion of the stop mechanism of the certain stop keys on a given coinhi piston, and Fig. G is a ciagraini'ii illustrated as such.

ment above the contact pin 9 whereby it maintains itself in such contact and supports the upper leaf 6 ofthe bellows so that the latter isdield extended whereas upon the contraction of the bellows as by opening the passage 3 to a vacuum, the switch arm' 12 yields laterally disengaging the shoulder from the contact pin 9 and looking it beneath or in engagement with the lower contact pinlO, as shown at' the left in Fig. 4. A very cheap and simple pneumatically operated switch is thus provided- Qrgans of a type to which my present improvements are adapted are provided, usually in a row-just beneath the keys of each manual, with a plurality of keys or combination pistons, as they are called, the object of which is to draw, by pressing any one of them, a certain combination, coupled to that particular one, of the stops on the manual simultaneously and without the necessity or drawing each stop individually. Certain combinations are used under certain circumstances and it is necessary to change the stop keys to be drawn by a given combination piston from time to time. This is done by first drawing the individual stop keys wanted in the combination, then pressing the combination piston to which they are to be coupled and simultaneously pressing what is termed a locking or general piston located at a convenient point, there being one on the console for each manual and each row of combination pistons. The stop keys are then returned and the locking piston released whereupon every time that particular combination piston is pressed independently of or without simultaneously depressing the general or locking piston, the same combination of stop keys is drawn with the one movement.

The present invention is shown diagrainmatically embodied in a mechanism by means of which these results are obtained and referring to Fig. 4, more particularly, 15 indicates a stop key pivoted at 16 and provided with bellows 17 and 18, the expansion of the former of which draws the stop, while similar action in the other returns it. The first is under the control of an electromagnet 19 and the second under'the control of a similar magnet 20, the windings of which are connected, respectively, by wires 21 and 22 to the contact pins 10 and 9 of the switch previously described. These circuits are both energized by the generator 23 and are both controlled by a combination piston 24, the function of which, in the present instancais merely that of a switch, as shown. Therefore, when the combination piston is pressed or drawn it closes a circuit from generator 23 through wire 25, piston. 24, wire elcctro-magnet 27 and wire 28, back to the generator." The electro-magnet'27 con trols a pneumatic 29 havinga contact plate 30 that closes contacts 31. Another circuit is thereby established from the generator through a wire 32 (considering the switch 1213 to be in the position shown in Fig. 4), wire 33, magnet 20, wire 22, contact .9, switch arni 12, switch arm 13, contact 11, wire 34, contacts 31 and back to the generator through wire 35. This will cause the bellows 18 of the stop key to operate and the latter to return from its drawn position. If, however, the switch arm 12 is held by its motor 4 in lowered position, the circuit will pass through the other magnet 19 and the lower contact pin 10 and cause the upper bellows 17 of the stop key to operate, drawing the latter.

The switches comprising the bellows or motors 4 are arranged in longitudinal and transverse rows, the former bei'n indicated in Fig. 1 by the letters A- Ai -A fi -A and the latter by the letters B-B, 18 -13 'B -B There is a row A-A, A -A l for each combination piston and one in each row for each stop key on the manual, the switches in rows AA controlling the same stop-key being arranged opposite each other so that the transverse rows BB, B B B -B all relate to the same stop key and there is a possible circuit, as above described, through each switch in that row to that stop key, each circuit under the control of a different combination piston 24. The passages 3 of the motors 4 in each transverse row B-B, B-B 13 -13 are all fed from a single wind chest 2, there being as many of these chests as there are rows B-B, B -B 13 -43 The passages 3 of ,each row A-A, A A Alf-A are, however, simultaneously opened or closed by a valve member having, in the present instance, the form of a slider 36 provided with an aperture 37 for each passage in that row.

Referring now to Fig. 5, the combination piston 24, when pressed, closes, at one point, an independent circuit to an electro-magnet 38 controlling a bellows 39 in a wind chest 40, which bellows or motor is connected at 41 with a slider 36 and the operation of the bellows draws the slider and operates all the motors 4 of the switches in one of the rows A-A. This circuit, however, passes through the beforementioned looking or general piston 42 which is also in the nature of a switch, the circuit being generator 23, wire 43, locking piston 42, wire 44, combination piston; wire45, magnet 38,.wire 46 and back to the generator. One locking piston 42 is sufficient. The locking piston. 42 alone closes another circuit from generator 23, locking'piston 42, wire 47 through electromagnets 48 and 49 and wire 50 back to the generator.- Thcse magnets 48 and 49, respectively, control the passage of wind from suitable sources of supply 51 and 52 into.

wind chests 53 and 54, the former at a posi lieved to make more intelligible the function of each, but in Fig. 6 both sets are shown joined together, a plurality of stop keys being shown as well as a plurality of combination pistons. In this view, which is for the most part diagrammatic, the additional stop key and ti additional combination piston, as well as circuits and parts controlling or under the control of each, are indicated by the same reference numerals as the parts of which they are duplicates, but are distinguished by prime marks in connection with the reference numerals. The view also illustrates that the several switches in each transverse row B-B, B B 13 -13 are arranged in parallel on the circuit of the operating mechanism of one stop key, While all the switches in Ea-3i longitudinal row AA, A -A A --A are all in parallel on a circuit elsewhere controlled by one particular combination piston. There may be as many combination pistons as are desired in view of the number of possible combinations that it is wished to provide for, although there need be only one locking piston 42 for all the combination pistons Zel, 24, as shown.
